The Lifehammer Safety Hammer Smart has been developed according to the highest possible technical standards. When the hammer head is pressed against the side or rear window, the ceramic hammer head automatically shatters the tempered glass. It features an advanced seat belt cutter with functionally orange-colored components for easy recognition of the glass breaker and safety cutter. The shape of the base is integrated with the hammer design. Easy and safe to use by adults and children. Break the side and/or rear car window in an easy and safe way. Caution! Do not use on laminated glass.
